1.8 = 1.80
If there is a 0 after any number in a decimal it has no value,
for example, 1.2323000 = 1.2323
I think you just need to draw a number line starting at one OR zero that goes up and explain why
Answer:
or
Step-by-step explanation:
Find the magnitude of :
Find the direction angle of :
Since is our reference angle, we determine our direction angle by verifying our angle is in Quadrant IV, which is where the vector is located. Therefore,
To represent a vector's magnitude and direction in trigonometric form, we use the form or .
In conclusion, the trigonometric form of the vector is:
or
Answer:
y = 7
Step-by-step explanation:
Mathematically, according to the Pythagoras’ theorem;
The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides
The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here
Thus, we have it that;
(√85 )^2= 6^2 + y^2
85 = 36 + y^2
y^2 = 85-36
y^2 = 49
y = √49
y = 7
